Here is the Atari Punk Console in Eurorack form! Originally designed by DIY electronics guru Forrest Mims III as the “Stepped Tone Generator”, the Atari Punk Console is one of the most famous and recognizable Lo-Fi synth circuits ever.

Using a single 556 dual timer IC with minimal part count, the Atari Punk Console circuit is a solid, time-tested noise generator capable of outrageous square wave madness!

Low part count = easy build for beginners!

Control Voltage (CV) input allows step sequencers and waveform generators to expand the sonic capabilities of the Atari Punk Console from drone to arpeggio-like dynamism. Use any variable voltage source from 0-Supply Voltage for some glitchy goodness! The APC modular version has two CV inputs that modulate the two square wave internal oscillators.
